Answer:

Option D: 3x2 +  2x - 1

Step-by-step explanation:

Given that:

=(5x2 - 5x + 3 )- (2x2 +7x- 4)

As we have to subtract them so by simplifying:

"-" sign will alter all signs in the bracket

= 5x2 - 5x + 3 - 2x2 + 7x - 4

Now by adding same terms

= 5x2 - 2x2 - 5x + 7x + 3 -4

= 3x2 +  2x - 1

i hope it will help you!

The office manager of First Tech Support borrowed $25,000 to purchase new computers for employees. The bank charges 6 percent in
Travka [436]

Given:

Amount borrowed (P)= $25000

Rate of interest (r)= 6%

Time (t)= 4 years.

To find:

The total interest the company pay in all.

Solution:

We know that,

A=P(1+r)^t

where, A is amount, P is principal, r is rate of interest and t is time period.

A=25000(1+\dfrac{6}{100})^4

A=25000(1.06)^4

A=25000(1.26247696)

A=31561.924


Now,

I=A-P

I=31561.924-25000

I=6561.924

Therefore, the total interest is $6561.924.

Given: 9x > -36.
balu736 [363]
<h2>Greetings!</h2>

Answer:

{x | x > -4}

Step-by-step explanation:

The direction of the < or > sign only changes when numbers are multiplied or divided by negatives.

Because to simplify 9x > -36 you only need to divide by 9, the sign stays the same and the numbers are simply divided:

\frac{9x}{9}  > \frac{-36}{9}

x > -4

So the solutuon set would be:

<h3>{x | x > -4}</h3>
<h2>Hope this helps!</h2>
